" Figure 1;

Fig. 4 is a bottom plan view of the structure shown in Figs. 1 and 2.

Fig. 5 is a side elevation of myfimproved nut before attachment;

4Fig. 6 is a section taken on the line G -Lof Fig. 5; and

Fig. 7 is a plan view of the blank from which the nut is formed ,afterl the4 shank has been drawn. f My invention relates to a nut similar to that f shown and described in United States Letters Patent No. 1,873,895 to Arthur W. Kimball, issued August 23, 1932,y and ymore particularly to an improved means for attachment of such a n nut to a support. 1 Heretofore nuts of the type shown in the patent referred to above havel been p attached by welding, nailing and even by screws. y These methods are rather expensive and there- `fore I have provided integral attaching means which simplify attachment.

My improved nut is formed from sheet metal and has a base I from which is drawn a tubular shank 2 preferably internally threaded as shown in Figs. 2 andv 6. At the edges of the base are integral flat fingers 3. The base is preferably rectangular in outline to provide a flange and the lingers extend inwardly from each side toward the center ofthe nut preferably on that side of 'the base flange I opposite the side from which 40 extends the shank 2. The fingers then extend y outwardly from the base flange` in spaced parallel relation and form a rectangular extension, as

shown in Figs. 1 and 5.

When attaching my improved nut toa support such as the thin sheet metal part 4 shown in Figs. 1, 2 and 3.1t is advisable to provide a rectangular aperture 5 about the size anu) shape of the cross-sectional area of the extension provided by the fingers 3. The lingers 3 are eni tered through the aperture 5 and the free ends are bent outwardly and downwardly against one face of the support I as illustrated. Thus, the

support 4 is clamped tightly between the inwardly bent portions of the fingers and the outwardly bent portions as shown. The nut is therefore held securely in place against dise placement by rotation or accidental axial movement so that a suitable screw may be threaded into the shank 2 to secure another part (not shown) in position. My device is simple, inexpensive, and efficient.

It is formed entirely from a single piece of sheet metal and can be made quite easily and in rela-A tively fast production.

While I have illustrated and described a preferred embodiment of my invention, I dov not wish to be limited thereby, because the scope of my invention is best defined by the following claims. f

I claim:A

l1. A sheet metal nut formed from a single .piece of metal and having a flange portion, a hollow threaded shank extending from said flange and a plurality of bendable fingers extending from the periphery of said flange inwardly parallel to the plane of said flange and then outwardly at right angles thereto `for the purpose described.

. 2. A sheet metal Vnut formed from a single piece of metal and having a iiange portion, a hollow threaded shank extending from said flange and a plurality of at'bendablengers extend' ing from the periphery of said ange inwardly parallel to the plane of said flange and then outwardly at right angles thereto for the purpose described, said extended portions of said fingers being arranged in the form of a rectangle to nt a' rectangular hole in a nut support. f
